Definitions

  • the present invention relates to a spacing member for a tooth implant, comprising a base portion for attachment to a fixture implanted in the jawbone, and an upper part with an essentially conical outer surface for attachment of a tooth prosthesis.
  • the base portion comprises a through hole for a spacing screw intended to engage with an internally threaded bore in the upper portion of the fixture to thereby form a first screw connection for locking the spacing member securely in a defined direction of deflection in relation to the fixture.
  • the upper part comprises a second screw connection for attachment of the tooth prosthesis, which screw connection forms a fixed angle in relation to the first screw connection.
  • angled spacers have been introduced in some cases.
  • the securing screw for the tooth bridge can sometimes end up in an unsuitable position.
  • the securing screw can be placed in a position which is more favorable from the point of view of appearance and from the point of view of dental technique.
  • Angled spacers with a fixed angle between the fixture and the prosthetic attachment screw are also already known, for example, from EP 0 323 421.
  • the spacing member is designed as a single part and has a conical base portion which can be securely locked in a defined direction of deflection in relation to the fixture by means of a first screw connection, a segment-shaped intermediate part, and a conical upper part with a second screw connection for attachment of the tooth prosthesis, the second screw connection forming a fixed angle, preferably within the range of 25°-40°, in relation to the first screw connection.
  • An angled spacer of this type is strong, comprises few parts and makes it easy for the prosthodontist to recover the correct position should the setting come loose.
  • the angled spacers with a fixed angle also have certain limitations. These limitations are that the angle is too great in many clinical cases.
  • the existing angled spacer may have an angle of about 30°, whereas a more desirable angle would be about 15°.
  • the upper conical attachment part must be made very much higher in order to provide room for the internal thread in the upper conical part. Such an increase in height is not desirable, since this would severely limit the usability of the component.
  • An object of the invention is therefore to solve the above problems and to provide an angled spacer which exhibits a smaller angle than previously, but in which today's basic solution, as regards a base portion and an upper attachment part formed in a single piece, can be retained, and which in addition is relatively simple to manufacture using current machining methods.
  • FIG. 1 shows a sectional side view of the angled spacing member
  • FIG. 2 shows an end view of the base portion of the spacing member
  • FIG. 3 shows how the spacing member cooperates with a spacing screw for attachment of the spacing member to a tooth implant (fixture), and
  • FIG. 4 shows the spacing member joined together with the fixture, and an attachment sleeve in the form of a conical cap for attachment of a tooth prosthesis.
  • the spacing member comprises a mainly downwardly narrowing, essentially conically shaped base portion 1 intended to cooperate with the upper portion of a fixture of the type which comprises an upper hexagon. Fixtures of this kind are already known and will therefore not be dealt with in detail here.
  • the base portion is arranged such that its line of symmetry (center line) 1a coincides with the line of symmetry of the fixture.
  • the base portion is further formed with an internal twelve-pointed geometry 2 which fits against the hexagon of the fixture, such that the spacing member, when turned, moves 30° instead of 60° between the directions of deflection.
  • the twelve-pointed geometry 2 in this way constitutes a rotational lock and provides twelve fixed directions of deflection for the spacing member.
  • the base portion has an outer annular support surface 3 which bears against the shoulder portion of the fixture.
  • the conical outer surface 4 connects with an even fit to the upper cylindrical side surface of the fixture, so that the surface below the gum level is completely smooth.
  • the base portion further comprises a through hole 5 for a spacing screw 6, see also FIG. 3, which engages with the internally threaded bore in the upper portion of the fixture in order to lock the spacing member securely to the fixture.
  • the hole 5 consists of a narrower cylindrical or conical part 19 and of a cylindrical widened part 25, the head 7 of the spacing screw, after it has been tightened, bearing against an upper, internal circular heel 8 in the spacing member between the narrower part and the widened part of the hole 5.
  • the base portion 1 of the spacing member thus corresponds in principle to the base portion of the spacing member which is shown in EP 0 323 421.
  • the base portion merges at the top directly into a conical upper part 9 for attachment of the prosthetic construction.
  • the line of symmetry 9a of the conical upper pat forms an angle ⁇ with the line of symmetry 1a of the base portion.
  • the deflection angle ⁇ preferably lies within the range of 15°-20°, in this embodiment 17°.
  • the base of the conical upper part 9 merges with the base portion 1 via an annular collar 10 which forms a support for a conical cap 11, see also FIG. 4.
  • the conical upper part 9 is provided with a threaded hole 12 for the screw connection which joins the spacing member to the conical cap 11 cast into the tooth bridge.
  • the screw connection is thus coaxial with this cap.
  • the outer surface of the conical upper part further comprises an inlet opening 13 for the spacing screw 6 so that the latter can be guided down through the hole 5 and screwed firmly in the fixture with the aid of a screwdriver which is also guided down through the inlet hole in the axial direction of the screw for the purpose of tightening the screw connection.
  • the inlet opening 13 is not a straight cylindrical hole forming a continuation of the cylindrical widened part 25 through the base portion 1, but instead the upper part 14 of the inlet opening is offset towards the center line 1a of the hole 5.
  • the material 14a remaining in the upper portion of the conical upper part is still sufficient for the threaded hole 12 for securing of the conical cap to be bored with a sufficient material thickness all round, despite the low angle of 15°-25°.
  • the offset d of the upper part 14 of the inlet opening is preferably adapted to a straight screwdriver of known construction for tightening the screw connection, i.e. the offset of the upper part 14 of the inlet opening in towards the center line of the hole is not so great that the screwdriver cannot be guided in the axial direction down through the hole for the purpose of tightening the screw connection.
  • the offset d of the upper part 14 of the inlet opening corresponds to the width of the circular heel 8 for the head of the spacing screw and in this case the inlet opening cuts in somewhat through the plane top surface of the conical upper part 9.
  • the offset d of the upper part 14 of the inlet opening can also be greater, so that the inlet opening is situated completely in the conical outer surface of the upper part 9.
  • an angled screwdriver has to be used for tightening the screw connection.
  • the screwdriver is in this case guided in through the opening in the conical limit surface at an angle which essentially corresponds to the angle ⁇ between the two screw connections.
  • the spacing screw 6 comprises a lower threaded portion 15 arranged to engage in the upper thread of the fixture, an elongate middle area 16, and a screw head 7 with a heel 17 underneath for bearing against the inner circular heel 8 in the spacing member.
  • the head 7 of the spacing screw merges with the middle area 16 via a short cylindrical portion 18 of slightly larger diameter.
  • FIG. 3 shows, step by step, how the spacing screw is guided through the hole 5 of the spacing member for attachment to the fixture. It is clear form FIGS. 3a and b that the direction of the spacing screw, then it is guided in through the spacing member, first coincides with the line of symmetry 1a.
  • the spacing screw 6 Since the upper part 14 of the inlet opening has been offset, the spacing screw 6 has to be angled slightly as its head 7 passes the inlet opening, see FIGS. 3c, d and e. As soon as the head of the spacing screw has passed through the inlet opening, its direction of introduction then once more coincides with the line of symmetry 1a, see FIGS. 3f, g and h. In FIG. 3h the spacing screw is in place and bears against the circular heel 8 with its head. In order to permit the angled positioning when the screw is being passed through the narrower part 19 of the hole 5 under the circular heel, i.e. under the screw head 7, this hole 19 is conical, i.e. it has a downwardly increasing diameter, see FIGS. 3c, d and f.
  • the cone angle is about 5°.
  • the screw head 7 of the spacing screw 6 is conical, narrowing towards the top, for two reasons: on the one hand, the introduction of the spacing screw part the offset inlet opening is facilitated if the maximum width of the screw head is kept short, and, on the other hand, a cylindrical screw head would extend beyond the conical limit surface of the spacing member if, for aesthetic reasons, a small spacer height was needed.
  • FIG. 3h and in FIG. 4 where a previously known circular-symmetrical, conical cap 11 has been attached to the spacing member with the aid of a screw 20 which engages in the upper threaded hole 12.
  • the cap rests with its wider, outwardly curved part 21 against the annular support surface 10 of the spacing member, and it additionally has the same function as the attachment sleeve 16 which is described in the EP 0 323 421.
  • the fixture 22 is of known construction, with an upper bore 23 for the spacing screw and an upper hexagon 24 which cooperates with the inner, twelve-pointed geometry 2, see above.
  • the spacing member is comparatively simple to manufacture.
  • a through hole with a fairly small diameter is formed, which corresponds to the narrow hole 19.
  • the cylindrical widened part 25 is formed, in a second machining operation, by means of the diameter in the base portion of the hole and in its upper part being extended up to a certain distance from the end plane of the conical upper part, where the hole merges with the narrower diameter via a collar 14b.
  • the result of this operation is therefore that the upper part of the through hole is offset in parallel, by a distance d, towards the center line of the hole.
  • the invention is not limited to the embodiment shown above by way of example, but instead can be varied within the scope of the patent claims which follow.
  • the essentially conical limit surface of the upper part of the spacing member can have different appearances, for example it can be stepped in shape, as long as it is accommodated within the conical cap which is secured over the spacer.
